SN74LVCH245ADBR

Buffers, Drivers, Receivers, Transceivers Overview

The SN74LVCH245ADBR is an octal bus transceiver from Texas Instruments featuring three-state outputs. It operates within a supply voltage range of 1.65 V to 3.6 V and supports bidirectional data transfer between two buses. The device includes direction control inputs to manage data flow and output enable inputs for bus isolation. It accepts TTL/CMOS input levels and provides LVTTL output levels, ensuring compatibility with mixed-voltage systems.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Provides bidirectional data transmission across eight channels with independent direction control
• Features three-state outputs that allow effective bus isolation when disabled
• Supports operation in mixed 3.3 V and 5 V system environments through compatible input levels

Buffers, Drivers, Receivers, Transceivers Applications

• Asynchronous communication between data buses
• Mixed voltage system interfacing
• Parallel signal buffering and driving

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant, as the 'DBR' suffix typically indicates a SOIC-20 tape and reel configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact speed grade and temperature range specified in the official datasheet to avoid functional mismatches.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component for designs requiring low-voltage operation down to 1.65 V with high drive capability. It is suitable for applications needing to bridge different logic families or voltage domains without external level shifters. Consider the propagation delay and output current specifications against your bus loading requirements to ensure signal integrity.

Buffers, Drivers, Receivers, Transceivers Part Context

This device belongs to the LVCH (Low-Voltage CMOS High-Speed) series by Texas Instruments. It is designed for high-speed digital applications where power consumption must be minimized while maintaining fast switching speeds. The octal configuration allows for efficient handling of wide data buses in compact surface-mount packages.
